National Volunteer Week
Thousands of events will be held across the country in May to say thank you to the 6 million Australians who volunteer their time. The week-long celebration will include breakfasts, morning/afternoon teas, and luncheons, as well as open days, award ceremonies, picnics, forums and training sessions.
